Patent CA-1329949-C (CA)
Inventor: IKEDA SADAYUKI
IPC: H04N5/341
Filed: 1986-11-25
Granted: 1994-05-31
Abstract: ABSTRACT OF THE DISCLOSURE A circuit for driving a CCD image sensor includes a high-speed pulse generating circuit generating a first high-speed pulse train (sweeping pulse train) having pulses to be used to discard non-signal charges during the vertical blanking period and a second high-speed pulse train (high-speed transfer pulse train) having pulses of a number equal to the number of the light-sensing elements in each row and used to quickly transfer the charges from the imaging area to the storage area in the vertical blanking period.  There is also included a gate pulse generating circuit generating a first gate pulse to take the accumulated charges out of each row of light-sensing elements at a point in time after the first high-speed pulse train is generated and before the second high-speed pulse train is generated and a second gate pulse to take out non-signal charges accumulated in each row of the light-sensing elements at an arbitrary point in time after the generation of the second high-speed pulse train and before the generation of the first high-speed pulse-train, during the field period (active video period). The invention shortens the charge-accumulation time in the imaging area without using a mechanical shutter.

Title: Vector and method for achieving high level expression in eukaryotic cells
Inventor: GILLIES STEPHEN D
IPC: C12N15/85
Filed: 1987-01-06
Granted: 1992-06-23
Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed are vectors for achieving high level expression in eucaryotic cells.  The vectors include an expressible gene encoding a protein product of interest, an expressible gene encoding a marker protein which permits selection of useful transformants, and an enhancer element, preferably a cellular enhancer element, which functions to increase the level of transcription of genes disposed on its 3' and 5' sides.  A blocking element is interposed between the enhancer element and the marker gene which shields the promoter of the marker gene from the transcription-stimulating function of the enhancer, thereby limiting the effect of the enhancer to transcriptions of the DNA encoding the protein product of interest.  Use of the vectors permits isolation of viable clones characterized by a very high level of expression of the protein of interest.

Abstract: A system (11) for interfacing a pay-per-view CATV system with the switched public network telephone system is disclosed.  In a conventional switched public network telephone system having at least one central office switch (10) and a plurality of subscriber loops (16) operatively coupled to the central office switch (10), each subscriber loop (16) is identified by an originating telephone number.  The subscriber selects a specific one of the scheduled television programming events by calling a telephone number which uniquely identifies the selected event.  The called and originating numbers are identified, digitized and combined to form a digital word.  The digital word is then transmitted to the CATV supplier (30).

Patent CA-1282281-C (CA)
Inventor: ELROD SCOTT A
IPC: B41J2/05
Filed: 1987-04-09
Granted: 1991-04-02
Abstract: ABSTRACT   Provision is made for selectively addressing individual crests of traveling or standing capillary surface waves to eject droplets from the selected crests on command. To that end, the addressing mechanisms of this invention locally increase the surface pressure acting on the selected crests and/or locally reduce the surface tension of the liquid within the selected crests. The preferred addressing mechanisms have sufficient spatial resolution to address a single crest substantially independently of its neighbors.       Discrete addressing mechanisms having a plurality of individual addressing elements are especially attractive for liquid ink printing and similar applications, not only because their individual addressing elements may be spatially fixed, but also because the spatial frequency of their addressing elements may be matched to the spatial frequency of the capillary wave. Such frequency matching enables selected crests of the capillary wave to be addressed in parallel, such as for line printing. Preferably, the capillary wave for a printer is a spatially stabilized standing wave, so that the crests and troughs of the capillary wave are locket in predetermined spatial locations.

Abstract: ABSTRACT           A blind fastener assembly suitable for use in joint assemblies including advanced composite material workpieces.  The blind fastener assembly includes a core pin having an enlarged head, an expander having a head and a tapered nose portion and being mounted to the core pin, and a frangible sleeve mounted to the core pin between the enlarged head and the expander.  The blind fastener assembly is insertable through aligned holes in the workpieces so that the head of the expander abuts the accessible side of the workpiece.  Relative longitudinal movement of the core pin and the expander nut causes the sleeve to expand over the tapered nose and to break into two pieces, one of the two pieces expanding over the other of the two pieces to provide a large bearing surface on the blind side of the workpieces.

Abstract: SINGLE EYEPIECE BINOCULAR MICROSCOPE                 ABSTRACT OF THE DISCLOSURE A single eyepiece binocular microscope (2) includes a microscope housing (4) having a generally horizontal base (6) and housing several optical elements. An objective lens (12) is positioned immediately above the specimen (16) and adjacent the base plane (8).  A first mirror (22), vertically above the objective lens, redirects the light down and away from the observer along a path (28) to intersect a second mirror (32) positioned adjacent the base plane.  The second mirror redirects the light along a third light path (34) up and towards the observer (40) for intersection with a rear projection screen (38).  A viewing chamber (44) shields the screen from ambient light for a brighter image and for an illusion of depth.  A second lens (24), positioned just behind the real image (26) of the first lens, provides a real image at the screen.  A third lens (46) at the viewing opening (48) creates a virtual image (50) between the second mirror and the rear projec-tion screen to aid the impression of depth.  The arrange-ment provides an impression to the viewer of looking into the instrument and at the specimen, an important consideration for use by children.
